Katherine Schwarzenegger, 21, Arnold and Maria’s eldest daughter, has broken her silence about her parents' divorce after 25 years.

Schwarzenegger opens up to Harper’s Bazaar about her parents, and how the separation and cheating scandal affected her family’s lives in the media.

"Me and my siblings have never really been in the spotlight growing up," she told the magazine. "My parents always really sheltered us, so when [the separation] started happening, it was like everything came out of nowhere overnight."

She says the media backlash began shortly after.

"I would go out to lunch, and literally 20 people would come and scream at me. And I'm like, this is so inappropriate; you're trying to provoke me to have an attack and say something crazy."

She spent time in London to escape the scandal where the split wasn’t as big of a deal. Still, she says she doesn’t pay any attention to tabloids.

"I see them, but I choose not to read the stories because I figure whether it's true or not, I don't need to," she explained. "I just focus on my family and everyone being okay instead of following the gossip."

Although she didn’t directly address the lovechild scandal, she says some people questioned what she publicly said in the beginning.

“Sometimes we forgive people because we want them back in our lives," she said she tweeted, which gained scrutiny. "Everyone was automatically like, 'You're forgiving your father for what he's done? It's too soon!' I'm like, 'I just think it's a nice quote.'"

"I try not to care about what other people necessarily think," she added.

She says she’s not taking sides during the divorce, although she admits, “I've always been way closer to my mom," adding the relationships with her parents are very different.

Despite the media and some Twitter backlash, she admits Twitter has become a way for people to reach out, and she appreciates that.

"When my parents announced they were separating, people on Twitter were like, 'Oh, how are you doing?' They said, 'How are you? We love you. We love your family.' And even if it's people you don't know, it's nice to hear people say that,” she continued. “So I responded, 'Thank you so much for your support in this difficult time,' which is definitely a difficult time. It made dealing with it so much easier.”

"I really do believe everything happens for a reason," she adds, "A lot of the time, it's hard to understand in the moment why things are happening, but I really do think that. I also like to think God doesn't really give you anything you can't handle."
